Ahh must this be in the Lake District?
A girl I work with went with her family to stay in a cottage in the Lake District over the Easter Weekend, and saw Renee acting as Potter. She didn't exactly get close to her (was maybe 10feet away) but said she is just so delicate looking and actually a lot prettier in the flesh.
Plus Renee shouted 'hi' and waved to them all, asking how they were and if they were enjoying staying there so she's quite high ranking as a nice celeb in my book!
